Specification of Letters Patent.

Patented May 5, 1914.

Application filed August 19, 1912. Serial No. 715,917.

My invention relates generally to mixing units and has for its object toprovide a unit which, when used ineonnection with the cylinder, intakeport or manifold of a hydrocarbon engine will substantially preventback-firing. V

Another object has been to provide a de-' vice which ma be used inconnection with the manifold pipe, intake port or cylinder of fuelmixture and consumption, and also one which may be connected with asuitable source of electric currentand thus bejheated, thereby making itpossible to easily start the engine. j 1

My invention comprises a plurality of members so arranged as to providea plurality of longitudinal passage ways, thus forming mixing unit.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which like characters of reference indicate likeparts throughout the several views of which:

Figure 1 is a erspective view of a rectangularly shaped unit which ismade of flat and'corrugated. sheets of material. Fig. 2 isa plan view ofa cylindrically shapedunit which is formed from flat and corrugatedsheets of material. Fig. 3 is a plan view with a partly finishedcircularly shaped unit which '1s formedo'f a flat and corrugated sheetof material, rolled in the form of a spiral. Fig. 4 shows two of mycircularly shaped units arranged foruse in the path of travel'of thefuel mixer betweenthe carbureter and the intake manifold, and also showsone of the units insulated from the casing and provided with a suitableelectric heating means to further accelerate the va porization of thefuel in coldwzather.

My units are each made of a plurality of flat sheets l5 and a pluralitof corrugated sheets 16, preferablyforme of sheet metal of any suitablematerial. These sheets are center of this unitand has central yalternately arranged and disposed one upon the other. The form of deviceshown in Fig. 1 is for use in chambers of squareor rectangular shape. InFig. 2 the sheetsof material forming the unit are wrapped about oneanother in concentric rings and is for use in circular shaped chambers.In Fig. 3 the unit is formed of a single sheet of flat material 15 and asingle sheet of corrugated,

material 16, which are rolled together in the form of a spiral. Thisconstruction makes it possible to form a unit of any diameter from onlytwo sheets of material, and thus provides a very convenient method ofmanufacture.

InFig. 4, I have adaptations of my show its use in connection with themanifold or intake pipe of a hydro-carbon engine. In this figure,- 45represents a fragmental portion of an intake manifold, and 46 afragmental portion of the pipe leading from. the carbureter to the saidintake manifold.

' 47 and 48 represent two of my va orizing units which are preferablydispose within a casing shown one of the many 49. This casingispreferably providedwith heads 50 and 51 which are secured to themanifold intake ipe 45 and pipe 46 respectively.- As the uel mixturepasses from the carburetor, to the intake manifold-it is obliged topass-through a plurality of longitudinal passage ways rovided by' myunit, and in this passage it, is more thoroughly mixed and atomized,thus making a richer mixture and also economizing on the fuel used.

- In Fig. 4 I show one of my units arranged to be heated by a current ofelectricity. In this figure, I have shown the unit 48 insulated from thecasing lating material 52.

mater1al,57 is also arranged throu 49 by a strip of insu- A strip ofinsulating h the disposed therein an insulated core 58, around which iswound a coil of resistance wire 59. Connected with the opposite ends ofthis coil are electricalv terminals 53, which pass through suitableinsulating bushings in the casing and are connected with a suitablesource of electric current. When an electric current is allowed to passthrough the coil of Wire 59, the unit is thereby heated and as .thevapor from the carbureter comesv in contact therewith,

it is also heated and more unit. In thisfigure I V jacket. 54: which isprovided with an-inlet' and outlet port 55 and 56, respectively. Thisjacket may be supplied with hot exhaust gases, hot wateror hot air andthus raise the temperature of the units and ac complish the same resultsas the electric heat-in means. 7

Obviously, if desired, one or more vaporizing units may be placed withinthe intake manifold, the intake ports or the cylinders of a hydro-carbonengine instead of being placed within a separate casing, as shown inFig. 4, when so arranged, the sameresults are accomplished as with theform shown and in-addition the engine is prevented from back-firing.

Having thus'described .my invention, it will be seen that my-deviceaccomplishes the results pointedout in the objects hereinbeforeenumerated. I Obviously, some modifications of the details herein shownand described may be made without departing from the spirit of myinvention claims and I the exact embodiment herein shown and described.

or the scope ofthe appended do not wish to be limited toand alternatelydisposed therewith, an insulated core in proximity to said unit and acoil of resistance wire supported by said core, whereby the unit will beheated and vaporization accelerated.

3. A mixing unit having a plurality'of corrugated sheets of material, aplurality of smooth sheets of material, said smooth sheets being incontact with said corrugated sheets and alternately disposed therewith,an insulated core disposed within said unit and a coil of resistancewire supported by said core, whereby the unit will porizationaccelerated.

In testimony whereof, I have hereunto signed my name in the scribingwitnesses.
